Langfuse Rate Limits

Langfuse cloud throttling is primarily quota-based on monthly units (traces, observations, scores). Enterprise accounts can negotiate custom rate limits. Self-hosted installations are limited only by the operator's own infrastructure.

Policies

Backoff Strategy
Honor 429 responses with exponential backoff and jitter; SDKs handle retry automatically.
Trace Batching
SDKs batch trace ingestion calls before flushing, reducing per-request overhead.
OpenTelemetry Path
Use the OTel ingestion endpoint where possible; it is the recommended, higher-throughput path.
